Abstract

The present invention relates to device, system and method for visualization of patient-related data. To enable a user, such as a caregiver, to quickly and easily recognize if the patient'"'"'s health conditions has become critical, the propose device comprises a processor for processing the obtained patient-related data for visualization. The processor is configured to generate time-dependent plots of at least two different patient-related parameters over time derived from the obtained patient-related data. Said plots are generated for common visualization in a common timing diagram on a display, wherein the scale, baseline, position and range of the plots are selected to visualize the plots in the common timing diagram without overlap at times, at which the parameter values of the respective parameters visualized by the plots are considered uncritical for the patient'"'"'s health condition, and to visualize a plot with overlap with another plot at times, at which the parameter values of the parameter of said plot are considered critical for the patient'"'"'s health condition.
